Virolaisiin naistenlehtiin kirjoittuva materialistinen maailma : Annen, Eesti Naisen ja Stiilin kansijuttujen tarkastelua kriittisen tekstintutkimuksen menetelmällä

Pro gradu -tutkielmassani tarkastelen Viron kolmen suurimman naistenlehden kansijuttuja systeemis-funktionaalisen kieliopin menetelmällä. Lehdet ovat Anne, Eesti Naine ja Stiil. Aineisto, tammikuussa 2003 ? syyskuussa 2004 ilmestyneet 55 artikkelia, on pääosin haettu lehtien omista internetarkistoista. Tutkin kansijuttuja systeemis-funktionaalisen kieliopin menetelmällä. Tavoitteenani on ollut selvittää, minkälaisia arvoja, asenteita ja maailmankuvia teksteihin kirjoittuu. Lähestyn kansijuttuja ideationaalisen, interpersoonaisen ja tekstuaalisen metafunktion näkökulmista. Kaikki kolme metafunktiota esiintyvät kielellisissä ilmiöissä yhtä aikaa. Mitä tahansa puhuttua tai kirjoitettua lausetta on mahdollista analysoida minkä tahansa metafunktion kannalta. Ideationaalinen metafunktio tarkoittaa yhtäältä sitä, minkälaisena maailma ja ilmiöt teksteissä kuvataan, toisaalta sitä, minkälaisia prosesseja teksteissä representoidaan. Interpersoonainen metafunktio tarkoittaa teksteihin kirjoittuvia suhteita, vuorovaikutusta ja identiteettejä, esimerkiksi toimittajan ja lukijan välistä suhdetta ja heidän roolejaan. Kun tekstiä tutkitaan tekstuaalisen metafunktion kannalta, siitä nostetaan esiin kieliopillisia, sanastollisia ja syntaktisia piirteitä, joista tekstit rakentuvat koherenteiksi kokonaisuuksiksi. Pro graduni kuuluu kriittisen tekstintutkimuksen alaan. Kriittinen tekstintutkimus on monitieteinen menetelmä, jonka tavoitteena on selvittää kielellisesti representoituja valtasuhteita sekä eksplisiittisesti ja implisiittisesti lauseisiin kirjoittuvia arvotuksia. Kriittisen tekstintutkimuksen tavoitteena on osoittaa, millä tavalla ihmisten ajattelua pystytään ohjaamaan ja hallitsemaan kielellisten ratkaisujen keinoin. Viron kolmen suurimman naistenlehden kansijutuille yhteinen piirre on materialistinen maailmankuva, joka ilmenee teksteissä muun muassa korostuneena kulutustottumusten, ulkonäön ja elämäntyylin kuvailuna. Tekstit ovat avoimen kaupallisia. Selkein osoitus kaupallisuudesta on tunnetuttujen vaate-, kosmetiikka ja automerkkien näkyminen teksteissä, luonnollisena osana juttua. Kansijuttujen haastateltavat ovat eri aloja edustavia, korkeasti koulutettuja, itsenäisiä ja näkyvissä asemissa vaikuttavia henkilöitä, valtaosaltaan naisia. Juttuihin he representoituvat perhettä, isänmaata ja uskontoa arvostavina perusarvojen kannattajina, joita esimerkiksi tasa-arvokysymykset, syrjäytyminen tai globalisaatio eivät kiinnosta. Keskeinen kysymys onkin journalistinen prosessi, jonka tuloksena kansijutut ovat syntyneet. Vaikka kansijutuissa näennäisesti äänessä ovat voimakkaat virolaisnaiset, voi rivien välistä ymmärtää, että tarinan kerrontaan vaikuttavat myös julkaisijoiden taloudelliset intressit.

Suomen Kuvalehden Hän-henkilöjutut tekstilajina

Tutkielma käsittelee Suomen Kuvalehden Hän-henkilöjuttuja tekstilajina. Lehti on itse nimennyt sarjan, mikä tukee ajatusta omasta tekstilajista. Marraskuusta 1989 lähtien Suomen Kuvalehdessä on ilmestynyt viikottain kahden aukeaman henkilöjuttu, jonka tekstin määrä ja jaottelu, otsikointi, taitto ja kuvitus ovat pysyneet lähes samana vuosien ajan. Jutut ovat pääosin tunnettujen suomalaisten haastatteluja. Hän-henkilöjutut ovat instituutio Suomen aikakauslehdistössä. Hän-henkilöjuttuja tarkastellaan tekstintutkimuksen keinoin. Teoreettisena viitekehyksenä on tekstilaji- eli genreteoria. Keskeiset teorialähteet ovat Swales (1990) ja Bhatia (1993). Työn aluksi Hän-henkilöjutut kontekstualisoidaan, mikä on olennaista tekstilajin tutkimisessa. Johdatuksessa perehdytään niin Hän-juttujen historiaan, Suomen Kuvalehden toimituksen näkemyksiin kuin journalistiikan oppikirjojen ohjeisiinkin. Hän-juttuja on ilmestynyt yli 700. Tutkimusaineisto rajataan pääosin vuoden 2003 juttuihin, mutta sarjan historiaa kerratessa juttuja tarkastellaan laajemmalti. Hän-logo, yhtenäiset otsikot ja tekstin asettelu ovat huomattavia tekstilajin määrittäjiä. Ne tekevät sarjaan toistuvuuden, jota vahvistetaan visuaalisesti. Hän-henkilöjuttujen valokuvia tarkastellaan Kressin ja van Leeuwenin visuaalisen kieliopin (1996) avulla. Kuvien säännönmukaisuus näkyy muun muassa niin, että vuoden 2003 Hän-juttujen kuvissa henkilö on useimmiten sijoitettu kuvan keskelle, ja tämä katsoo lähes poikkeuksetta suoraan kohti. Lisäksi henkilö on pienessä kuvassa rajattu tiukemmin kuin jutun pääkuvassa, joka täyttää 2/3 jutun ensimmäisestä aukeamasta. Kertojan havaittavuus tekstissä on omalaatuista Hän-henkilöjutuissa. Aihetta tarkastellaan käymällä tarkasti läpi yhden Hän-jutun koko kerronta. Taustalla on kirjallisuustieteen narratologian näkemys fyysisen tekijän ja kertojan eriävyydestä. Hän-henkilöjutussa Maskun Kalustetalon toimitusjohtajasta Toivo Sukarista (Suomen Kuvalehti 39/2003) havaitaan, että kertoja on jatkuvasti läsnä. Ainoastaan havaittavuuden aste vaihtelee. Kertoja esittää kysymyksiä, hän käskee lukijaa, huudahtaa, havainnoi kohdehenkilöä ja tapahtumaympäristöä, ottaa kantaa, esittää yhteenvetoja ja käyttää nimeämisen valtaa. Tuloksia kertojan havaittavuudesta testataan 15:een Hän-henkilöjuttuun. Niistä 12 on vuodelta 2003, lisäksi mukana on yksi juttu vuodelta 1990, 1995 ja 2000. Jutuista hahmotetaan tekstilajin kertojaa, joksi kirjallisuustieteen sisäistekijää kutsun. Tekstilajin kertojan rajoitukset ovat väljät, mutta havaittavuus näyttää olevan sidoksissa käsiteltävän henkilön tunnettuuteen. Mitä tunnetumpi henkilö, sitä enemmän kertoja voi tekstissä näyttäytyä. Lopuksi kartoitetaan Hän-henkilöjuttujen aloituksia. Niissä hahmottuu päätyyppejä, kuten tapahtuma-aloitus, havaintoaloitus ja referointialoitus, mutta tarkkarajaista luokittelua niistä ei voi tehdä. Osaksi sen perusteella voidaan väittää, että Hän-henkilöjutuilla ei ole kaavaa. Avainsanat: tekstintutkimus, tekstilaji, genre, henkilöjuttu, haastattelu, kertoja, sisäistekijä, aloitukset

The role of catechol-O-methyltransferase (COMT) and the effects of COMT inhibition in brain and in cardiovascular and renal pathophysiology

Catechol-O-methyltransferase (COMT) metabolizes catecholamines such as dopamine (DA), noradrenaline (NA) and adrenaline, which are vital neurotransmitters and hormones that play important roles in the regulation of physiological processes. COMT enzyme has a functional Val158Met polymorphism in humans, which affects the subjects COMT activity. Increasing evidence suggests that this functional polymorphism may play a role in the etiology of various diseases from schizophrenia to cancers. The aim of this project was to provide novel biochemical information on the physiological and especially pathophysiological roles of COMT enzyme as well as the effects of COMT inhibition in the brain and in the cardiovascular and renal system. To assess the roles of COMT and COMT inhibition in pathophysiology, we used four different study designs. The possible beneficial effects of COMT inhibition were studied in double-transgenic rats (dTGRs) harbouring human angiotensinogen and renin genes. Due to angiotensin II (Ang II) overexpression, these animals exhibit severe hypetension, cardiovascular and renal end-organ damage and mortality of approximately 25-40% at the age of 7-weeks. The dTGRs and their Sprague-Dawley controls tissue samples were assessed with light microscopy, immunohistochemistry, reverse transcriptase-polymerase chain reaction (RT-PCR) and high-pressure liquid chromatography (HPLC) to evaluate the tissue damages and the possible protective effects pharmacological intervention with COMT inhibitors. In a second study, the consequence of genetic and pharmacological COMT blockade in blood pressure regulation during normal and high-sodium was elucidated using COMT-deficient mice. The blood pressure and the heart rate were measured using direct radiotelemetric blood pressure surveillance. In a third study, the effects of acute and subchronic COMT inhibition during combined levodopa (L-DOPA) + dopa decarboxylase inhibitor treatment in homocysteine formation was evaluated. Finally, we assessed the COMT enzyme expression, activity and cellular localization in the CNS during inflammation-induced neurodegeneration using Western blotting, HPLC and various enzymatic assays. The effects of pharmacological COMT inhibition on neurodegeneration were also studied. The COMT inhibitor entacapone protected against the Ang II-induced perivascular inflammation, renal damage and cardiovascular mortality in dTGRs. COMT inhibitors reduced the albuminuria by 85% and prevented the cardiovascular mortality completely. Entacapone treatment was shown to ameliorate oxidative stress and inflammation. Furthermore, we established that the genetic and pharmacological COMT enzyme blockade protects against the blood pressure-elevating effects of high sodium intake in mice. These effects were mediated via enhanced renal dopaminergic tone and suggest an important role of COMT enzyme, especially in salt-sensitive hypertension. Entacapone also ameliorated the L-DOPA-induced hyperhomocysteinemia in rats. This is important, since decreased homocysteine levels may decrease the risk of cardiovascular diseases in Parkinson´s disease (PD) patients using L-DOPA. The Lipopolysaccharide (LPS)-induced inflammation and subsequent delayed dopaminergic neurodegeneration were accompanied by up-regulation of COMT expression and activity in microglial cells as well as in perivascular cells. Interestingly, similar perivascular up-regulation of COMT expression in inflamed renal tissue was previously noted in dTGRs. These results suggest that inflammation reactions may up-regulate COMT expression. Furthermore, this increased glial and perivascular COMT activity in the central nervous system (CNS) may decrease the bioavailability of L-DOPA and be related to the motor fluctuation noted during L-DOPA therapy in PD patients.

Uncertainty in forest simulators and forest planning systems

The forest simulator is a computerized model for predicting forest growth and future development as well as effects of forest harvests and treatments. The forest planning system is a decision support tool, usually including a forest simulator and an optimisation model, for finding the optimal forest management actions. The information produced by forest simulators and forest planning systems is used for various analytical purposes and in support of decision making. However, the quality and reliability of this information can often be questioned. Natural variation in forest growth and estimation errors in forest inventory, among other things, cause uncertainty in predictions of forest growth and development. This uncertainty stemming from different sources has various undesirable effects. In many cases outcomes of decisions based on uncertain information are something else than desired. The objective of this thesis was to study various sources of uncertainty and their effects in forest simulators and forest planning systems. The study focused on three notable sources of uncertainty: errors in forest growth predictions, errors in forest inventory data, and stochastic fluctuation of timber assortment prices. Effects of uncertainty were studied using two types of forest growth models, individual tree-level models and stand-level models, and with various error simulation methods. New method for simulating more realistic forest inventory errors was introduced and tested. Also, three notable sources of uncertainty were combined and their joint effects on stand-level net present value estimates were simulated. According to the results, the various sources of uncertainty can have distinct effects in different forest growth simulators. The new forest inventory error simulation method proved to produce more realistic errors. The analysis on the joint effects of various sources of uncertainty provided interesting knowledge about uncertainty in forest simulators.

Urban energy fluxes in Helsinki and their high frequency spectral corrections

Inadvertent climate modification has led to an increase in urban temperatures compared to the surrounding rural area. The main reason for the temperature rise is the altered energy portioning of input net radiation to heat storage and sensible and latent heat fluxes in addition to the anthropogenic heat flux. The heat storage flux and anthropogenic heat flux have not yet been determined for Helsinki and they are not directly measurable. To the contrary, turbulent fluxes of sensible and latent heat in addition to net radiation can be measured, and the anthropogenic heat flux together with the heat storage flux can be solved as a residual. As a result, all inaccuracies in the determination of the energy balance components propagate to the residual term and special attention must be paid to the accurate determination of the components. One cause of error in the turbulent fluxes is the fluctuation attenuation at high frequencies which can be accounted for by high frequency spectral corrections. The aim of this study is twofold: to assess the relevance of high frequency corrections to water vapor fluxes and to assess the temporal variation of the energy fluxes. Turbulent fluxes of sensible and latent heat have been measured at SMEAR III station, Helsinki, since December 2005 using the eddy covariance technique. In addition, net radiation measurements have been ongoing since July 2007. The used calculation methods in this study consist of widely accepted eddy covariance data post processing methods in addition to Fourier and wavelet analysis. The high frequency spectral correction using the traditional transfer function method is highly dependent on relative humidity and has an 11% effect on the latent heat flux. This method is based on an assumption of spectral similarity which is shown not to be valid. A new correction method using wavelet analysis is thus initialized and it seems to account for the high frequency variation deficit. Anyhow, the resulting wavelet correction remains minimal in contrast to the traditional transfer function correction. The energy fluxes exhibit a behavior characteristic for urban environments: the energy input is channeled to sensible heat as latent heat flux is restricted by water availability. The monthly mean residual of the energy balance ranges from 30 Wm-2 in summer to -35 Wm-2 in winter meaning a heat storage to the ground during summer. Furthermore, the anthropogenic heat flux is approximated to be 50 Wm-2 during winter when residential heating is important.

4QMMT - The Problem of the Epilogue

The main focus of this study is the epilogue of 4QMMT (4QMiqsat Ma aseh ha-Torah), a text of obscure genre containing a halakhic section found in cave 4 at Qumran. In the official edition published in the series Discoveries of the Judaean Desert (DJD X), the extant document was divided by its editors, Elisha Qimron and John Strugnell, into three literary divisions: Section A) the calendar section representing a 364-day solar calendar, Section B) the halakhot, and Section C) an epilogue. The work begins with text critical inspection of the manuscripts containing text from the epilogue (mss 4Q397, 4Q398, and 4Q399). However, since the relationship of the epilogue to the other sections of the whole document 4QMMT is under investigation, the calendrical fragments (4Q327 and 4Q394 3-7, lines 1-3) and the halakhic section also receive some attention, albeit more limited and purpose oriented. In Ch. 2, after a transcription of the fragments of the epilogue, a synopsis is presented in order to evaluate the composite text of the DJD X edition in light of the evidence provided by the individual manuscripts. As a result, several critical comments are offered, and finally, an alternative arrangement of the fragments of the epilogue with an English translation. In the following chapter (Ch. 3), the diversity of the two main literary divisions, the halakhic section and the epilogue, is discussed, and it is demonstrated that the author(s) of 4QMMT adopted and adjusted the covenantal pattern known from biblical law collections, more specifically Deuteronomy. The question of the genre of 4QMMT is investigated in Ch. 4. The final chapter (Ch. 5) contains an analysis of the use of Scripture in the epilogue. In a close reading, both the explicit citations and the more subtle allusions are investigated in an attempt to trace the theology of the epilogue. The main emphases of the epilogue are covenantal faithfulness, repentance and return. The contents of the document reflect a grave concern for the purity of the cult in Jerusalem, and in the epilogue Deuteronomic language and expressions are used to convince the readers of the necessity of a reformation. The large number of late copies found in cave 4 at Qumran witness the significance of 4QMMT and the continuous importance of the Jerusalem Temple for the Qumran community.

Salaisen evankelistan salaliitto : Uusin keskustelu Klemens Aleksandrialaisen kirjeestä Theodorokselle

This thesis is an assessment of the hoax hypothesis, mainly propagated in Stephen C. Carlson's 2005 monograph "The Gospel Hoax: Morton Smith's Invention of Secret Mark", which suggests that professor Morton Smith (1915-1991) forged Clement of Alexandria's letter to Theodore. This letter Smith claimed to have discovered as an 18th century copy in the monastery of Mar Saba in 1958. The Introduction narrates the discovery story of Morton Smith and traces the manuscript's whereabouts up to its apparent disappearance in 1990 following with a brief history of scholarship of the MS and some methodological considerations. Chapters 2 and 3 deal with the arguments for the hoax (mainly by Stephen C. Carlson) and against it (mainly Scott G. Brown). Chapter 2 looks at the MS in its physical aspects, and chapter 3 assesses its subject matter. I conclude that some of the details fit reasonably well with the hoax hypothesis, but on the whole the arguments against it are more persuasive. Especially Carlson's use of QDE-analysis (Questioned Document Examination) has many problems. Comparing the handwriting of Clement's letter to Morton Smith's handwriting I conclude that there are some "repeated differences" between them suggesting that Smith is not the writer of the disputed letter. Clement's letter to Theodore derives most likely from antiquity though the exact details of its character are not discussed in length in this thesis. In Chapter 4 I take a special look at Stephen C. Carlson's arguments which propose that Morton Smith hid clues of his identity to the MS and the materials surrounding it. Comparing these alleged clues to known pseudoscientific works I conclude that Carlson utilizes here methods normally reserved for building a conspiracy theory; thus Carlson's hoax hypothesis has serious methodological flaws in respect to these hidden clues. I construct a model of these questionable methods titled "a boisterous pseudohistorical method" that contains three parts: 1) beginning with a question that from the beginning implicitly contains the answer, 2) considering everything will do as evidence for the conspiracy theory, and 3) abandoning probability and thinking literally that everything is connected. I propose that Stephen C. Carlson utilizes these pseudoscientific methods in his unearthing of Morton Smith's "clues". Chapter 5 looks briefly at the literary genre I title "textual puzzle -thriller". Because even biblical scholarship follows the signs of the times, I propose Carlson's hoax hypothesis has its literary equivalents in fiction in titles like Dan Brown's "Da Vinci Code" and in academic works in titles like John Dart's "Decoding Mark". All of these are interested in solving textual puzzles, even though the methodological choices are not acceptable for scholarship. Thus the hoax hypothesis as a whole is alternatively either unpersuasive or plain bad science.

Circadian Rhythm Disruptions and Health

The doctoral thesis defined connections between circadian rhythm disruptions and health problems. Sleep debt, jet-lag, shift work, as well as transitions into and out of the daylight saving time may lead to circadian rhythm disruptions. Disturbed circadian rhythm causes sleep deprivation and decrease of mood and these effects may lead to higher accident rates and trigger mental illnesses. Circadian clock genes are involved in the regulation of the cell cycle and metabolism and thus unstable circadian rhythmicity may also lead to cancer development. In publications I-III it was explored how transitions into and out of the daylight saving time impact the sleep efficiency and the rest-activity cycles of healthy individuals. Also it was explored whether the effect of transition is different in fall as compared to spring, and whether there are subgroup specific differences in the adjustment to transitions into and out of daylight saving time. The healthy participants of studies I-III used actigraphs before and after the transitions and filled in the morningness-eveningness and seasonal pattern assessment questionnaires. In publication IV the incidence of hospital-treated accidents and manic episodes was explored two weeks before and two weeks after the transitions into and out of the daylight saving time in years 1987-2003. In publication V the relationship between circadian rhythm disruption and the prevalence of Non-Hodgkin lymphoma was studied. The study V consisted of all working aged Finns who participated in the national population census in 1970. For our study, all the cancers diagnosed during the years 1971-1995 were extracted from the Finnish Cancer Register and linked with the 1970 census files. In studies I-III it was noticed that transitions into and out of the daylight saving time disturbs the sleep-wake cycle and the sleep efficiency of the healthy participants. We also noticed that short sleepers were more sensitive than long sleepers for sudden changes in the circadian rhythm. Our results also indicated that adaptation to changes in the circadian rhythm is potentially sex, age and chronotype-specific. In study IV no significant increase in the occurrence of hospital treated accidents or manic episodes was noticed. However, interesting observations about the seasonal fluctuation of the occurrence rates of accidents and manic episodes were made. Study V revealed that there might be close relationship between circadian rhythm disruption and cancer. The prevalence of Non-Hodgkin lymphoma was the highest among night workers. The five publications included in this thesis together point out that disturbed circadian rhythms may have adverse effect on health. Disturbed circadian rhythms decrease the quality of sleep and weaken the sleep-wake cycle. A continuous circadian rhythm disruption may also predispose individuals to cancer development. Since circadian rhythm disruptions are common in modern society they might have a remarkable impact on the public health. Thus it is important to continue circadian rhythm research so that better prevention and treatment methods can be developed. Keywords: Circadian rhythm, daylight saving time, manic episodes, accidents, Non-Hodgkin lymphoma 11

Risk factors for open angle glaucoma; a clinical and molecular genetic study

Glaucoma, optic neuropathy with excavation in the optic nerve head and corresponding visual field defect, is one of the leading causes for blindness worldwide. However, visual disability can often be avoided or delayed if the disease is diagnosed at an early stage. Therefore, recognising the risk factors for development and progression of glaucoma may prevent further damage. The purpose of the present study was to evaluate factors associated with visual disability caused by glaucoma and the genetic features of two risk factors, exfoliation syndrome (ES) and a positive family history of glaucoma. The present study material consisted of three study groups 1) deceased glaucoma patients from the Ekenäs practice 2) glaucoma families from the Ekenäs region and 3) population based families with and without exfoliation syndrome from Kökar Island. For the retrospective study, 106 patients with open angle glaucoma (OAG) were identified. At the last visit, 17 patients were visually impaired. Blindness induced by glaucoma was found in one or both eyes in 16 patients and in both eyes in six patients. The cumulative incidence of glaucoma caused blindness for one eye was 6% at 5 years, 9% at 10 years, and 15% at 15 years from initialising the treatment. The factors associated with blindness caused by glaucoma were an advanced stage of glaucoma at diagnosis, fluctuation in intraocular pressure during treatment, the presence of exfoliation syndrome, and poor patient compliance. A cross-sectional population based study performed in 1960-1962 on Kökar Island and the same population was followed until 2002. In total 965 subjects (530 over 50 years) have been examined at least once. The prevalence of exfoliation syndrome (ES) was 18% among subjects older than 50 years. Seventy-five of all 78 ES-positives belonged to the same extended pedigree. According to the segregation and family analysis, exfoliation syndrome seemed to be inherited as an autosomal dominant trait with reduced penetrance. The penetrance was more reduced for males, but the risk for glaucoma was higher in males than in females. To find the gene or genes associated with exfoliation syndrome, a genome wide scan was performed for 64 members (28 ES affected and 36 controls) of the Kökar pedigree. A promising result was found: the highest two-point LOD score of 3.45 (θ=0.04) in chromosome18q12.1-21.33. The presence of mutations in glaucoma genes TIGR/MYOC (myocilin) and OPTN (optineurin) was analysed in eight glaucoma families from the Ekenäs region. An inheritance pattern resembling autosomal dominant mode was detected in all these families. Primary open angle glaucoma or exfoliation glaucoma was found in 35% of 136 family members and 28% were suspected to have glaucoma. No mutations were detected in these families.

Genetic Variation and Clinical Manifestations in Inflammatory Bowel Disease

Crohn s disease (CD) and ulcerative colitis (UC), collectively known as inflammatory bowel disease (IBD), are characterised by chronic inflammation of the gastrointestinal tract. IBD prevalence in Finland is approximately 3-4 per 1000 inhabitants with a peak incidence in adolescence. The symptoms of IBD include diarrhoea, abdominal pain, fever, and weight loss. The precise aetiology of IBD is unknown but interplay of environmental risk factors and immunologic changes trigger the disease in a genetically susceptible individual. Twin and family studies have provided strong evidence for genetic factors in IBD susceptibility, and genetic factors may be more prominent in CD than UC. The first CD susceptibility gene was identified in 2001. Three common mutations R702W, G908R, and 1007fs of the CARD15/NOD2 gene are shown to associate independently with CD but the magnitude of association varies between different populations. The present study aimed at identifying mutations and genetic variations in IBD susceptibility and candidate genes. In addition, correlation to phenotype was also assessed. One of the main objectives of this study was to evaluate the role of CARD15 in a Finnish CD cohort. 271 CD patients were studied for the three common mutations and the results showed a lower mutation frequency than in other Caucasian populations. Only 16% of the patients carried one of the three mutations. Ileal location as well as stricturing and penetrating behaviour of the disease were associated with occurrence of the mutations. The whole protein coding region of CARD15 was screened for possible Finnish founder mutations. In addition to several sequence variants, five novel mutations (R38M, W355X, P727L, W907R, and R1019X) were identified in five patients. Functional consequences of these novel variants were studied in vitro, and these studies demonstrated a profound impairment of MDP response. Investigation of CARD15 mutation frequency in healthy people across three continents showed a large geographic fluctuation. No simple correlation between mutation frequency and disease incidence was seen in populations studied. The occurrence of double mutant carriers in healthy controls suggested that the penetrance of risk alleles is low. Other main objectives aimed at identifying other genetic variations that are involved in the susceptibility to IBD. We investigated the most plausible IBD candidate genes including TRAF6, SLC22A4, SLC22A5, DLG5, TLR4, TNFRSF1A, ABCB1/MDR1, IL23R, and ATG16L1. The marker for a chromosome 5 risk haplotype and the rare HLA-DRB1*0103 allele were also studied. The study cohort consisted of 699 IBD patients (240 CD and 459 UC), of which 23% had a first-degree relative with IBD. Of the several candidate genes studied, IL23R was associated with CD susceptibility, and TNFRSF1A as well as the HLA-DRB1*0103 allele with UC susceptibility. IL23R variants also showed association with the stricturing phenotype and longer disease duration in CD patients. In addition, TNFRSF1A variants were more common among familial UC and ileocolonic CD. In conclusion, the common CARD15 mutations were shown to account for 16% of CD cases in Finland. Novel CARD15 variants identified in the present study are most likely disease-causing mutations, as judged by the results of in vitro studies. The present study also confirms the IL23R association with CD susceptibility and, in addition, TNFRSF1A and HLA-DRB1*0103 allele association with UC of specific clinical phenotypes.

Effects of Metabolic Risk Factors and Type 1 Diabetes on Brain Glucose and Brain Metabolites

The metabolic syndrome and type 1 diabetes are associated with brain alterations such as cognitive decline brain infarctions, atrophy, and white matter lesions. Despite the importance of these alterations, their pathomechanism is still poorly understood. This study was conducted to investigate brain glucose and metabolites in healthy individuals with an increased cardiovascular risk and in patients with type 1 diabetes in order to discover more information on the nature of the known brain alterations. We studied 43 20- to 45-year-old men. Study I compared two groups of non-diabetic men, one with an accumulation of cardiovascular risk factors and another without. Studies II to IV compared men with type 1 diabetes (duration of diabetes 6.7 ± 5.2 years, no microvascular complications) with non-diabetic men. Brain glucose, N-acetylaspartate (NAA), total creatine (tCr), choline, and myo-inositol (mI) were quantified with proton magnetic resonance spectroscopy in three cerebral regions: frontal cortex, frontal white matter, thalamus, and in cerebellar white matter. Data collection was performed for all participants during fasting glycemia and in a subgroup (Studies III and IV), also during a hyperglycemic clamp that increased plasma glucose concentration by 12 mmol/l. In non-diabetic men, the brain glucose concentration correlated linearly with plasma glucose concentration. The cardiovascular risk group (Study I) had a 13% higher plasma glucose concentration than the control group, but no difference in thalamic glucose content. The risk group thus had lower thalamic glucose content than expected. They also had 17% increased tCr (marker of oxidative metabolism). In the control group, tCr correlated with thalamic glucose content, but in the risk group, tCr correlated instead with fasting plasma glucose and 2-h plasma glucose concentration in the oral glucose tolerance test. Risk factors of the metabolic syndrome, most importantly insulin resistance, may thus influence brain metabolism. During fasting glycemia (Study II), regional variation in the cerebral glucose levels appeared in the non-diabetic subjects but not in those with diabetes. In diabetic patients, excess glucose had accumulated predominantly in the white matter where the metabolite alterations were also the most pronounced. Compared to the controls values, the white matter NAA (marker of neuronal metabolism) was 6% lower and mI (glia cell marker) 20% higher. Hyperglycemia is therefore a potent risk factor for diabetic brain disease and the metabolic brain alterations may appear even before any peripheral microvascular complications are detectable. During acute hyperglycemia (Study III), the increase in cerebral glucose content in the patients with type 1 diabetes was, dependent on brain region, between 1.1 and 2.0 mmol/l. An every-day hyperglycemic episode in a diabetic patient may therefore as much as double brain glucose concentration. While chronic hyperglycemia had led to accumulation of glucose in the white matter, acute hyperglycemia burdened predominantly the gray matter. Acute hyperglycemia also revealed that chronic fluctuation in blood glucose may be associated with alterations in glucose uptake or in metabolism in the thalamus. The cerebellar white matter appeared very differently from the cerebral (Study IV). In the non-diabetic men it contained twice as much glucose as the cerebrum. Diabetes had altered neither its glucose content nor the brain metabolites. The cerebellum seems therefore more resistant to the effects of hyperglycemia than is the cerebrum.

Eläytymisestä omiin tarinoihin : Televisiosarja katsojien keskustelussa

From sympathetic understanding to own stories. TV-series in the conversation of its viewers. The purpose of this study is to analyze viewers' conversations about TV-series as a practice in which viewers construct meaning to TV-series. In the tradition of British Cultural Studies this study understands that viewer has an active role in interpreting and constructing meaning to TV-series. In the tradition of feminist studies this study understands that gender is being constructed in social and cultural practices. In reception studies, the viewing of TV-series has usually been analyzed as a practice which is embedded at home and in a family. The studies are often based on interviews of viewers, and the analysis of the construction of meaning is based on interview material where the viewers most often talk about their viewing habits and the likes and dislikes of TV-shows and -characters. This study extends the reception and interpretation of TV-series from home to the moments of interaction between viewers. It is quite common to hear how people talk also outside of home about television and the programmes they have watched. In this study the construction of meaning is being studied in viewers' conversations. The method of analysis is conversation analysis which studies the ordered properties of everyday forms of social interaction. The data has been collected in a workplace where four women watched together (and without the presence of a researcher) two TV-series, American sitcom Golden Girls and Finnish family drama Ruusun aika (Time of a Rose), and afterwards had time and chance for discussion. There was neither a questionnaire nor an agenda for the women to discuss. The analysis of the conversation brings up three themes. In the orientation discussions the viewers aim to construct frames in which it makes sense to talk about the TV-series. The frames have mostly to do with the genre of the TV-series. The second theme is concerned with the viewers' aim to achieve sympathetic understanding of the characters in the TV-series. The third theme extends and transfers the conversation about TV-series to real or imaginary stories of own life. In the conversation the reception of a TV-series appears as being in motion: in the orientation discussions the viewers move towards the series, in the character-discussions the viewers move within the world of the series, and when telling their own stories the viewers move away from the TV-series towards their own lives. In the conversations there appears also a distinction in gender-constructions. When the viewers talk about motherhood, they adopt a serious and moralistic tone. When they talk about female sexuality and relationships between women and men they adopt carnevalistic and humorous tone. There are examples of these kinds of gender-constructions also in other studies of Finnish gender culture. Motherhood means the responsibility to good upbringing; relationships with men include something unpredictable and problematic which one handles at best in a humorous way.

Gender, Politics and Democratisation in Cameroon

Gender perceptions, religious belief systems, and political thought have excluded women from politics, for ages, around the world. Combining feminist and modernisation theorists in my theoretical framework, I examine the trends in patriarchal Europe and I highlight the gender-sensitive model of the Nordic countries. Retracing local gender patterns from precolonial to postcolonial eras in sub-Saharan Africa, I explore the links between perceptions, needs, resources, education and women's political participation in Cameroon. Democratisation is supposed to open up political participation, to grant equal opportunities to all adults. One ironic feature of the liberalisation process in Cameroon has been the decrease of women in parliamentarian representation (14% in 1988, 6% in 1992, 5% in 1997 and 10% in 2002). What social, cultural and institutional mechanisms produced this paradoxical outcome, the exclusion of half the population? The gender complementarity of the indigenous context has been lost to male prevalence privileged by education, church, law, employment, economy and politics in the public sphere; most women are marginalised in the private sphere. Nation building and development have failed; ethnicism and individualism are growing. Some hope lies in the growing civil society. From two surveys and 21 focus groups across Cameroon, in 2000 and 2002, some significant results of the processed empirical data reveal low electoral registration (34.5% women and 65.9% men), contrasted by the willingness to run for municipal elections (33.3 % women and 45.2% men). The co-existence of customary and statutory laws, the corrupt political system and fraudulent practices, contribute to the marginalisation of women and men who are interested in politics. A large majority of female respondents consider female politicians more trustworthy and capable than their male counterparts; they even foresee the appointment of a female Prime Minister. The Nordic countries have institutionalised gender equality in their legislation, policies and practices. France has improved women's political inclusion with the parity laws; Rwanda is another model of women's representation, thanks to its post-conflict constitution. From my analysis, Cameroonian institutions, men and more so women, may learn and borrow from these experiences, in order to design and implement a sustainable and gender-balanced democracy.

Personporträttet som tidningsgenre : En närläsningsstudie med fokus på innehållsliga teman, berättarkonventioner och kön

The thesis The portrait interview as a newspaper genre. A qualitative close reading focussing on topical motifs, conventions of narration, and gender defines the portrait interview as a newspaper genre and analyses how the personalities in the portraits are constructed textually. The main body of material consists of 107 portrait interviews in two morning newspapers, Dagens Nyheter (published in Stockholm, Sweden) and Hufvudstadsbladet (published in Swedish in Helsinki, Finland), during two one-week periods (week 46/1999 and week 38/2002). There is also complementary material of 59 portraits from four magazines. The study is carried out within the research traditions of journalistic genre studies, gender and journalism, and critical text analysis. It is comprised of a qualitative close reading focussing on content (topical motifs or themes), conventions of narration, and gender. The methods used to carry out the study are qualitative close reading and quantitative content analysis. The analysis identifies the stylistic elements that differentiate the portrait genre from other journalistic genres, as well as from the autobiographical genre, and explores what opportunities and limitations these elements present for the inclusion of even more women protagonists in the portrait genre. The portrait interview is an exception from the critical mission of journalism in general, with its position as a genre of politeness. Since a typical characteristic of the portrait interview genre is that it pays tribute to the protagonist, the genre reveals the kind of personalities and lives that are seen as admirable in society. Four levels of portrait interview are defined: the prototype portrait, the pure portrait, the hybrid portrait and the marginal portrait. The prototype is a raw version of a portrait that fulfils the criteria but may be lacking in content and stylistics. The pure portrait does not lack these qualities and resembles an ideal portrait. The hybrid is a borderline case which relates to another genre or is a mixture between the portrait and some other genre, most commonly the news genre. The marginal portrait does not fulfil the criteria, and can therefore be seen as an inadequate portrait. For example, obituaries and caricatures are excluded if the protagonist s voice is never quoted. The analysis resulted in three factors that in part help to explain why the portrait interview genre has somewhat more female protagonists than journalistic news texts do in general. The four main reasons why women are presented somewhat more in the portrait genre than in other journalistic genres are: (i) women are shown as exceptions to the female norm when, for example, taking a typical male job or managing in positions where there are few women; (ii) women are shown as representing female themes ; (iii) use of the double bind as a story-generating factor; and (iv) the intimisation of journalism. The double bind usually builds up the narration on female ambiguity in the contradiction between private and public life, for example family and career, personal desire and work. The intimisation of journalism and the double bind give women protagonists somewhat more publicity also because of the tendency of portrait interviews to create conflicts within the protagonist, as an exception to journalism in general where conflicts are created or seen as existing between, for example, persons, groupings or parties. Women protagonists and their lives create an optimal narration of inner conflicts originating in the double bind as men are usually not seen as suffering from these conflicts. The analysis also resulted in gendered portrait norms: The feminine portrait norm and the masculine portrait norm or more concretely, professional life and family life as expectation and exception. Women are expected to be responsible parents and mediocre professionals, while men are expected to be professionals and in their free time engaging fathers. Key words: journalism, genre, portrait interview, gender, interview, newspaper, women s magazine.

Stor Anna, Liten Anna och tio andra personporträtt : Om innehållsliga och språkliga mönster i en mediegenres kvinnobeskrivningar

The aim of this licentiate thesis is to analyse how femininity is constructed in twelve portrait interviews of women in the dailies Dagens Nyheter (Stockholm) and Hufvudstadsbladet (Helsinki) in September 1996, and to explore the portrait interview as a media genre. The qualitative analysis has a feminist and constructionist perspective and is connected to critical text analysis. It was carried out on two levels: first, femininity is identified on the linguistic level by choice of words, and second on the level of content (topical motifs/themes). The portrait interview as a genre constitutes a third dimension in the analysis: The aim is not towards the identification of femininity, but rather towards the identification of the portrait interview a relatively unexplored media genre. References (Swedish: omtal) to the principal character (or protagonist) are traced mainly through reference chains which consist of names, pronouns and substantive phrases. The interviewees were referred to by their full names in Dagens Nyheter (with the exception of the oldest and youngest interviewees, both of whom were mainly referred to by their first names), while the style of reference varied more in Hufvudstadsbladet. The position of the principal character was also analysed through her relation in the text to minor characters from her working life and from her private life. These minor characters maintained their subordinate positions in all of the portraits except that of the youngest principal character, in which the subsidiary voices became at least as strong as the voice of the principal character. Three frequently-recurring topical motifs occurred in the portraits: The first involved explanations for the principal character s success divided into three categories, agent, affect and ambition, the second concerned using journeys or trips as symbols for turning points in life, and the third referred to the ambiguity in the contradiction between private (family/other private life) and public (work) life. This ambiguity is connected to the portrait interview as a text type (genre) which features conclusions at the end of portraits, which in turn is characteristic of reportage. However, the analysis showed that the conclusions of the portrait interviews often also included elements of ambiguity. This was evident in the contradictions be14 tween private and public life that arose in the portrait interviews that focused on these two spheres. The portraits that focused on the principal character s public life showed ambiguity on a more general level concerning questions about being a woman and having a profession, and they often ended with a description of some details of her private life. The women in the portraits were all constructed as being successful, in terms of having achieved direct success, reflective success or success in the form of life wisdom. The women of direct success were described as ambitious individuals with no sidetracks on their life paths, while those of reflective success were described as active heroines who had received help from different agents, who could use their affects as enriching ingredients in life, but who in the end had control over their own lives (life stories). The elderly women were constructed as having achieved life wisdom and their portraits were focused upon the past. The portrait interview as a genre is characterised by journalistic freedom (in relation to the more strict news genre), by a now room (Swedish nurum ) where the journalist meets the principal character (usually via spoken dialogue that she or he transforms into written text to be read by a mass-media audience) and by the relatively closed structure of the portrait. The portrait is relatively independent in relation to the news genre and in relation to the context of what has previously been written, what is being written at the time and what will be written in the future the principal character does not need to belong to the newspaper s usual gallery of actors. Furthermore, the principal character is constructed as being independent in relation to the subsidiary characters and other media actors. The conflict is within the principal character herself and within her life story, unlike the news genre in which equal actors are in conflict with each other. The portrait is also independent in relation to the news lifespan; the publishing timetable is not as strict as in the news genre, but is still dependent on the factors initiating the portrait. The enclosures consist of a raw analysis of two of twelve portrait interviews and of copies of all portraits.
